SCREWLESS TYPE-WRITER BASE-BOARD.

Specification of Letters Patent.

Patented March' 3, 1908.

Application filed August 5. 1907- Serial No. 387.135.

The object of the invention is to provide a typewriter base-board havingmeans arranged thereon whereby a typewriting machine may be quicklysecured thereto and held in position thereon.

With this object in view the invention consists of certain novelfeatures of construction, combination and arrangements of parts as willbe more fully described and particularly pointed out in the appendedclaims.

In the accompanying drawings, Figure 1 is a perspective view of atypewriter base-board constructed in accordance with the invention Fig.2 1s a vertical cross sectional view on the line 22 of Fig. 1; Fig. 3 isa detail sectional view through a portion of the board, and one I of thespring catches for holdin the typewriter in place on the board; an Fig.4 is a detail view of one of the spring catches removed from the board.Referring more particularly to the draw-- ings, 1 denotes thebase-board, which may be of any suitable construction, and which, ifdesired, may form the hinged top or leaf of the desk on which thetypewriter is tobe supported.

Formed in the upper side of the board are circular recesses ordepressions, 2, said recesses bein arranged in osition to receive thefeet of the machine. disposed cushions 3, which are preferabl formed offelt or other soft yielding mater'ia Around the recesses 2 are securedsockets, 4, said sockets being screwed or otherwise secured to theboard. In arrang'ing' the typewriter on the board, the feet of the sameare adapted to be engaged with the sockets, the latter being ofsufficient depth to firmly hold oard.

In order that the machine may be firmly held in place when the board istilted, suitable fastening devices are provided, said den the recesses 2are and prevent the slipping of the machine on the vices consisting ofspring-projected catches, 5, which are in the form of hooks, the billsof which project outwardly toward the outer edges of the board, and areadapted to engage with the side bars of the typewriter frame. Thecatches 5 are provided on their lower' ends with lateral projections oroffsets, which are pivotally mounted between the parallel ears orlugs,6, of fastening devices, 7,

which are screwed or otherwise secured to the board. Between the end ofthe hook adjacent to the offset portion thereof, and upper side of thefastening devices, 7, and between the ears or lugs, 6, is arranged a.coiled spring, 8, the opposite ends of which are seated in recesses, 9,formed in the lower end of devices, said recesses holding the spring inplace; The tension of the springs 8 1s exerted to force the hooksoutwardly until the lower edge of the offset portion thereof engages theupper side of the fastening devices,

7. Said engagement limits the outward movement of the hooks, and holdsthe same in a substantially vertical position.

The upper sides or edges of the bills of the hooks are beveled .orinclined outwardly so that when the typewriter is seated upon the board,the side bars of the frame will engage the upper ends of the hooks andforce the same inwardly until said side bars have passed thebills of thehooks, after which the the hook and the upper side of the fasteningsprings 8 will automatically engage the bills with the side bars of themachine frame, thus securely fastening the machine on the board.

By means of the fastening devices constructed as herein shown anddescribed, a typewriter may be quickly secured to the board without theuse of screws or clamps.

When the machine has thus been secured to' the board, the latter may betilted or swung downwardly-to any position without danger of the machinefalling off; The devices thus form an efficient and reliable fasteningmeans for securing typewriters to the hinged tops or leaves oftypewriter desks in which the machines are dropped or tilted downwardlyinto the desk when not in use.

Having thus fully described my invention, what I claim as new and desireto secure by LettersePatent, is: 1
